Synonyms: Cemented carbide, Sintered carbide, Tungsten carbide, Cermet, Hard metal Intended Uses: Cutting tools, Wear parts Manufacturer: The Ultra-met Company 120 Fyffe Street Urbana, OH (937) Emergency Phone: (937) Section 2: Hazards Identification Classification: Within the meaning of the OSHA Hazardous Communication Standard (29 CFR 1910:1200) this product is considered a manufactured article and is not considered a hazard when used under normal conditions. Signal Word: Warning Hazard Statement: Grinding this product will produce dust which may be harmful in contact with eyes or skin, if inhaled, or swallowed. Emergency Overview: Sintered Tungsten Carbide with Cobalt and/or Nickel Binder is a dark gray solid metal with no odor. During normal operation and usage, cemented carbide products do not present inhalation or ingestion hazards. However grinding this material will generate dusts and mists that are considered hazardous by the OSHA Hazard Communication Standard (29 CFR ). Potential Health Effects: May cause eye irritation. May cause skin irritation or allergic skin rash. May cause irritation of the upper respiratory system. May cause systemic effects or chronic effects. Potential Environmental Effects: No data available at this time.

Dust (H232) Full text of H-phrases: See Section 16 Section 4: First Aid Measures Grinding cemented tungsten carbide product will produce dust of potentially hazardous ingredients which can be inhaled, swallowed or come in contact with the skin or eyes. First Aid Procedures: Flush eyes immediately with large amounts of water, occasionally lifting upper and lower lids, until no evidence of chemical remains. If irritation persists, seek medical attention. Wash thoroughly with soap and water and isolate from exposure. If irritation persists, seek medical attention. Move to fresh air. If symptoms of pulmonary involvement develop (i.e. coughing, wheezing, shortness of breath), remove from exposure and seek medical attention If substantial quantities are swallowed, dilute with a large amount of water, induce vomiting, and seek medical attention. Note to Physicians: Medical Conditions aggravated by long term exposure include chronic pulmonary, upper respiratory tract, and skin disorders. Target Organs are the respiratory system, skin, bladder, kidneys, and eyes. Primary Routes of Entry are through skin contact, eye contact, inhalation, or ingestion. Section 5: Fire-fighting Measures Flammable Properties: Cemented carbides are not a fire hazard. However dusts and mists generated in grinding operations may present a fire or explosion hazard if allowed to accumulate and are exposed to high temperatures or ignition sources. Particle size and dispersion in air determine reactivity. However, this is not expected to be a problem under normal handling conditions. Flash Point: Not applicable Suitable Extinguishing Media: Remove oxygen by sealing container or by smothering with dry sand, dry dolomite, use an ABC type fire extinguisher or flood with water. Move container from fire area if possible. Protection of Firefighters

3 Page 3 of 6 December 4, 2015 Specific Hazards Arising from Chemicals: May generate toxic metal fumes when heated. Protective Equipment and Precautions for Firefighters: For a fire contained to a small area, use a respirator approved for toxic dust and fumes. For a large fire, firefighters should use self-contained breathing apparatus. Section 6: Accidental Release Measures Personal Precautions: If airborne dust is present, ventilate area and use personal protection recommended in Section 8. Environmental Precautions: Material is not hazardous to the environment. Methods for Clean-Up: Clean up using methods that avoid dust generation such as a vacuum with HEPA filter, wet mop, or wipe. If airborne dust is generated use an appropriate NIOSH approved respirator. Place in suitable clean, dry container for later disposal or reclamation. Section 7: Handling and Storage Handling: Maintain good housekeeping practices to prevent dust accumulation during grinding. Avoid dispersion of grinding dust and mist into the air. Do not breathe dust. If airborne dust is generated use an appropriate NIOSH approved respirator. Avoid contact with skin, eyes, or clothing. Wash hands thoroughly after handling, before eating or smoking. Do not shake clothing, rags, or other items to remove dust. Dust should be removed by washing or vacuuming with appropriate filters. Storage: There is no specific storage requirement for end-user products. Section 8: Exposure Controls / Person Protection Exposure Guidelines Material OSHA PEL (1) ACGIH TLV (2) Tungsten Carbide (insoluble compounds) 5 mg/m 3 5 mg/m 3 Cobalt (dust and fume) 0.1 mg/m mg/m 3 Tantalum Carbide (metal and oxide dust) 5 mg/m 3 5 mg/m 3 Titanium Carbide (TiC) 5 mg/m 3 None established Niobium Carbide (NbC) None established None established Chromium Carbide (Cr 2 C 3 ) 1 mg/m mg/m 3 Vanadium Carbide (VC) None established None established Nickel (metal and insoluble compounds) 1 mg/m mg/m 3 Molybdenum (Mo) Not available 10 mg/m 3 (1) The OSHA PEL is the employee s time-weighted average exposure in any 8 hour work shift of a 40 hour week which may not be exceeded. (2) The ACGIH TLV is the time-weighted average concentration for an 8 hour workday in a 40 hour week to which nearly all workers may be repeatedly exposed with adverse effect. Engineering Controls: Use local exhaust ventilation that is adequate to limit personal exposure to airborne dust to levels that do not exceed the PEL or TLV. If such equipment is not available, use respirators as specified in Avoid contact with skin, eyes, and clothing. Wash hands thoroughly after handling and before eating or smoking. Personal Protective Equipment (PPE)

4 Page 4 of 6 December 4, 2015 Safety glasses with side shields are recommended. Protective apron and gloves or barrier creams are recommended when contact with dust or mist is likely. Prior to donning gloves, wash hands thoroughly. Use an appropriate NIOSH approved respirator when airborne dust concentrations exceed the appropriate PEL or TLV. All applicable requirements set forth in 29 CFR should be met.

Hazardous Decomposition Products: Not applicable Possibility of Hazardous Reactions: Will not occur under normal conditions. Section 11: Toxicological Information Can cause irritation or conjunctivitis. Can cause irritation or allergic skin rash due to cobalt or nickel sensitization. Certain skin conditions, such as dry skin, may be aggravated by exposure. Cobalt: Dusts or mists can cause irritation of the nose and throat. can results in an allergic reaction in individuals previously sensitized, causing difficult breathing. Dusts or mists also have the potential for causing transient or permanent respiratory or pulmonary diseases, including occupational asthma, pulmonary fibrosis, and interstitial pneumonitis in some individuals. It is reported that cobalt dust is the most probable cause of such respiratory diseases. Reports have also indicated a lack of correlation between onset of symptoms, length of exposure, and the development of interstitial pneumonitis. Symptoms may include a productive cough, wheezing, shortness of breath, chest tightness, dyspnea, and retrosternal pain.

5 Page 5 of 6 December 4, 2015 Conditions Aggravated by Exposure Nickel: Acute toxicity from nickel inhalation can cause headache, sore throat, and hoarseness. Nickel is also suspected of causing nasal and lung cancer. Symptoms may include pain, bleeding, nasal obstruction, vision impairment, weight loss, and voice resonance change. of significant amounts of cobalt has the potential of causing blood, heart, and other organ problems. The LD50 for cobalt is 6,171 mg/kg (oral, rat). Current scientific information indicates no adverse effects are likely from ingestion of small amounts of nickel dust generated from this product. The LD50 for nickel is 5 g/kg (oral, rat). Lung and other pulmonary and skin conditions may be aggravated by exposure. Carcinogenicity.
